Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
A connector with a measurable plugging distance is used for detecting the plugging distance of the connector.
As shown in fig. 1, the connector includes a connector plug 1 and a connector socket 2, and one or more sets of capacitance displacement sensors 3 are correspondingly disposed on the connector plug 1 and the connector socket 2. In this embodiment, the capacitance displacement sensors 3 are provided in two sets, and the two sets of capacitance displacement sensors 3 are respectively disposed on two sides of the plugging end of the connector plug 1 and the connector socket 2. Two sets of capacitance displacement sensor 3 set up respectively in the both sides of connector plug 1 and connector socket 2 insertion end, can enlarge the insertion error of connector plug 1 and connector socket 2, are favorable to improving the precision of inserting the state detection of closing to the connector.
The capacitance displacement sensor 3 comprises a pin terminal 3.1 and a jack terminal 3.2 correspondingly plugged with the pin terminal 3.1.
As shown in fig. 2, the pin terminal 3.1 mainly comprises a pin insulating head 3.11, a pin electrode 3.12, and a pin conducting wire 3.13, wherein the pin insulating head 3.11 and the pin conducting wire 3.13 are located at two ends of the pin electrode 3.12, and the outer diameter of the pin insulating head 3.11 is larger than the outer diameter of the pin electrode 3.12.
As shown in fig. 3, the jack terminal 3.2 mainly comprises a jack insulating sleeve 3.21, a jack electrode 3.22 and a jack conducting wire 3.23, wherein the jack insulating sleeve 3.21 and the jack conducting wire 3.23 are located at two ends of the jack electrode 3.22, and the inner diameter of the jack insulating sleeve 3.21 is smaller than that of the jack electrode 3.22.
The pin terminal 3.1 and the jack terminal 3.2 do not have the matching direction, and the pin terminal 3.1 can be arranged on the connector plug 1 or the connector socket 2. In this embodiment, the pin terminal 3.1 is arranged on the connector plug 1, the plug insulator 4 is arranged on the connector plug 1, and the plug insulator 4 is provided with an insulating mounting hole for mounting the pin terminal 3.1; the jack terminal 3.2 is arranged on the connector socket 2, the socket insulator 5 is arranged on the connector socket 2, and the socket insulator 5 is provided with an insulating mounting hole for mounting the jack terminal 3.2. The pin terminal 3.1 and the jack terminal 3.2 are respectively provided with a mounting step corresponding to the respective insulating mounting hole, and the pin terminal 3.1 and the jack terminal 3.2 are mounted in the respective corresponding insulating mounting holes through the respective mounting steps. The insulating mounting hole is used for fixing the pin terminal 3.1 and the jack terminal 3.2, so that the pin terminal 3.1 and the jack terminal 3.2 can be coaxially inserted; secondly, the pin terminal 3.1 is electrically insulated from the plug shell 6, and the jack terminal 3.2 is electrically insulated from the socket shell 7, so that the pin terminal 3.1 and the jack terminal 3.2 are prevented from short circuit when the plug shell 6 is inserted into the socket shell 7.
When the connector plug 1 is inserted into the connector socket 2, the pin terminals 3.1 of the two groups of capacitance displacement sensors 3 are correspondingly inserted into the jacks of the jack terminals 3.2. As shown in fig. 4, during insertion, the pin insulator 3.11 is inserted into the insertion hole of the insertion hole terminal 3.2 and is in sliding contact with the inner wall of the insertion hole electrode 3.22; the inner wall of the jack insulator 3.21 fits over the outer wall of the pin terminal 3.1 and is in sliding contact with the outer wall of the pin electrode 3.12. Because the outer diameter of the pin insulating head 3.11 is larger than the outer diameter of the pin electrode 3.12 and the inner diameter of the jack insulating sleeve 3.21 is smaller than the inner diameter of the jack electrode 3.22, the pin electrode 3.12 and the jack electrode 3.22 are not in electrical contact in the inserting and combining process, and a constant radial gap is always reserved between the pin electrode 3.12 and the jack electrode 3.22 in the inserting and combining process.
After the connector plug 1 and the connector socket 2 are plugged, the capacitance displacement sensor 3 has a structural basis of a capacitance element because a constant radial gap exists between the pin electrode 3.12 and the jack electrode 3.22. When the same voltage is applied to the two sets of capacitance displacement sensors 3 from the device end, the two sets of capacitance displacement sensors 3 will have charges and function as capacitance elements. The equipment end accessible obtains inserting of contact pin terminal 3.1 and jack terminal 3.2 and closes the distance to the detection that the realization inserted and closes the distance to the connector to the detection of capacitance displacement sensor 3 capacitance value.
Based on the connector with the measurable plugging distance, the invention also discloses a method for testing the plugging distance of the connector, which is used for testing and judging whether the plugging distance of the connector is in a set area or not so as to ensure that the connector can be plugged correctly.
The following describes the method for testing the insertion distance of the connector in two embodiments.

S2: the capacitance of the two groups of capacitance displacement sensors 3 is detected by a detection circuit at the equipment end, and capacitance values C1-0.91 pF and C2-0.93 pF are obtained;
s3: according to a calculation formula of the pinhole type capacitor:

As shown in fig. 5, the displacement of the pin terminal 3.1 in the socket terminal 3.2 is the insertion distance between the connector plug 1 and the connector socket 2; the calculation formula of the pinhole type capacitor shows that the inserting distance and the capacitance C are in a linear relationship. Therefore, the detected capacitance C is the insertion distance between the connector plug 1 and the connector receptacle 2.
S4: the detection circuit at the device end compares displacement amounts X1 and X2 with the insertion setting area, Y1 and Y2 are two end points of the insertion setting area respectively, Y1 is 5mm, and Y2 is 7 mm;
x1 is more than or equal to 5 and less than or equal to 7, and X2 is more than or equal to 5 and less than or equal to 7;
then, the detection circuit at the device end judges that the plugging distance between the connector plug 1 and the connector socket 2 meets the requirement, and the plugging of the connector plug 1 and the connector socket 2 is correct.
Example 2:
the method for testing the insertion distance of the connector comprises the following steps:
s1: after the connector plug 1 is plugged with the connector socket 2, the same voltage is applied to the two groups of capacitance displacement sensors 3, so that the two groups of capacitance displacement sensors 3 are respectively charged; in this embodiment, the receptacle terminal 3.2 is grounded and the pin terminal 3.1 has a positive charge.
S2: the capacitance of the two groups of capacitance displacement sensors 3 is detected by a detection circuit at the equipment end, and capacitance values C1-0.93 pF and C2-1.22 pF are obtained;
s3: according to a calculation formula of the pinhole type capacitor:
Figure BDA0002253764130000071
calculating the displacement X1-8 mm and X2-6 mm of the pin terminal 3.1 in the socket terminal 3.2;
in the formula: the pin terminal 3.1 has an outer diameter d of 1.9mm
The outer diameter of the jack terminal 3.2 is D; d is 2mm
The dielectric constant of the medium between the two polar plates is omega; omega 0.00885PF/mm (air)
S4: the detection circuit at the device end compares the displacement amounts X1 and X2 with the insertion setting region, and Y1 and Y2 are two end points of the insertion setting region, respectively, if both are satisfied:
x1 is more than or equal to 5 and less than or equal to 7, and X2 is more than 7;
then, the detection circuit at the device end judges that the insertion distance between the connector plug 1 and the connector socket 2 does not meet the requirement, and the insertion of the connector plug 1 and the connector socket 2 is skewed, which is the insertion transition.
According to the two embodiments, whether the plugging distance of the connector is in a set area or not can be tested and judged through the capacitance displacement sensor and the detection circuit of the equipment end, so that the problems that the plugging of the connector is not in place, or the equipment cannot work, the connector is damaged and potential quality hazards possibly occur due to plugging skew are solved.
The detection circuit at the equipment end can test and judge whether the plugging distance of the connector is in a set area or not, and can judge whether the plugging is not in place or is excessive or is caused by the fact that the plugging is skewed. The judgment is very important for distinguishing the connection reliability of the connector, and particularly, the influence of the connection quality of the connector on equipment can be quickly eliminated during equipment maintenance.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
